A picture signal processing circuit is composed of a picture memory, such as a field memory, having one input port for receiving an input picture signal and two distinct and independent output ports; a timing control circuit is designed to control the respective reading operations through the first and second output ports in such a manner that one output signal is shifted by one horizontal line period with respect to the other output signal, both output signals being supplied to an operating circuit, such as a vertical enhancer, for processing picture signals of a plurality of horizontal lines.
